使用NewtonSoft获取特定的Json字段

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;

namespace JsonParsingExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // JSON字符串示例
            string json = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";

            // 使用JObject解析JSON
            JObject jObject = JObject.Parse(json);

            // 获取特定字段的值
            string name = (string)jObject["name"];
            int age = (int)jObject["age"];
            string city = (string)jObject["city"];

            // 打印获取到的字段值
            Console.WriteLine("Name: " + name);
            Console.WriteLine("Age: " + age);
            Console.WriteLine("City: " + city);

            Console.ReadLine();
        }
    }
}
